Architect Lina Bo Bardi focused on public architecture, while other women architects in the 20th century usually worked in the residential and interior fields. Comparing her lives and activities with those of Lilly Reich, Eileen Gray, and Charlotte Perriand, Bo Bardi’s career has three characteristics. First, her affiliation with various networks including theatrical groups, which was influenced by her shifting bases. Second, her activities in magazines, which allowed her not to be passive in architectural discussions. Third, the gradual re-evaluation of crafts in her age, which were once neglected due to the appreciation of architectural works by male stars.
